How would i write the line of equation for (0.5,4.5) and (8,0.5)

Step-by-step explanation:y – y1 = m(x – x1)     * substitute (-0.5, 4.1) for x1 and y1

y - (4.1) = (0.8)(x - (-0.5))    

y - 4.1 = 0.8(x + 0.5)     * distribute the 0.8

y - 4.1 = 0.8x + 0.4     * add 4.1 to both sides

y = 0.8x + 4.5

this is the example hope this helped!

check the picture below.

well, the angle at the vertex d is clearly not a right-angle, let's check for the one at the vertex f which does look like,   however if it's indeed, that means ef is perpendicular to df, in which case their slopes will be negative reciprocal of each other.

so the negative reciprocal of the slope of ef is 1, however the slope of df is not 1, is 1/2, so nope, they're not perpendicular lines.

3,6 and 7.

step-by-step explanation:

a) unit place of 37 is 7

so the unit place of cube of 37 will be

7³= 343=3

the answer is 3.

b) unit place of 56 is 6, so the unit place of cube of 56 will be

6³= 216=6

the answer is 6.

c) unit place of 133 is 3, so the unit place of cube of 133 will be

3³= 27= 7.

the answer is 7.
